ROUTING-MACHINE Specification of Letters Patent.

Patented July 21, 1908.

Application filed January 21, 1905. Serial No. 242,191.

To all whom it may concern:

7 Be it known that I, VERNON BOYLE, a citizen of the United States, and resident of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Routing-Machine, of which the following is a specification.

My invention relates to routing machines and, more particularly to a routing machine in which cylinders of difierent sizes, as well as a flat table, may be brought into position to support the plate during the operation of the routin tool on it.

A practica embodiment of my invention is represented in the accompanying drawings, in which Figure 1 is a view in front elevation of so much of the routing machine as is necessary to illustrate my invention; Fig. 2 is a view of the same in end elevation; Fig. 3 is a longitudinal section in the plane of the line AA of Fig. 2; Fig. 4 is a top plan view of the fiat table for supporting t e plate; Fig. 5 is a section in detail of the clamp for engaging one ed e of the plate when resting on the flat table, and Fig. 6 is a section in detail of the clamp for engaging the opposite edge of the plate.

My present invention provides for mounting a plurality of cylinders, in the present instance two, and a flat, table on a common support and so arranged that either one of the cylinders or the table may be swun into position with respect to the cutting too without re uiring the interchange of cylin ders as has heretofore been common.

The u right pillar which forms the main support or the operating parts of the router is denoted by 1 and is provided with a head piece 2 on which the cutter supporting mechanism is mounted.

On the side of the pillar 1 there is a track 3 along which a cylinder sup orting slide 4 may be moved vertically to firing the cylinder into proper position to adjust the cylinder in the proper relation to the cutter.

The slide 4 and parts carried thereby are adjusted vertically by means of a screw 5 which asses downwardly through a bracket 6 on t e pillar, a nut 7 being engaged with the screw 5 and having its periphery developed into bevel gear 8 which registers with a bevel ear 9 on a shaft 10 provided with a hand w eel 11. The combined wheel and nut 7 and 8 rests with its face on top of the bracket 6 and by the engagement of the nut with the screw 5 supports the slide 4 and its parts. The weight of the slide 4 and the arts carried thereby is such that they will eed downwardly under. the influence of gravity alone when the nut 7 is turned in a direction to ermit them to do so.

From the s ide 4 there projects a taper axle 12 and on this axle a sleeve 13 bears at its inner and outer ends. The sleeve 13 is provided with cylinder and table supporting arms which radiate therefrom as follows The arms 14 and 15 (see Fig. 1) which support, respectively, one end of each of two cylinders as well as a pair of bifurcated arms 16 (see Fig. 2) for supporting a flat table are preferably formed integral with the sleeve 13 while the arms 17 and 18 which support the opposite ends of the cylinders are conveniently formed integral with a hub 19 which is keyed onto the end of the sleeve 13 and rotates together with the sleeve. The cylinder carried by the arms 14 and 17 is denoted by 20 and the cylinder carried by the arms 15 and 18 is denoted by 21. The cylinder 20 is of less diameter than the clylinder 21 for the purpose of supporting a plate having a curve ,vided with a hollow trunnion 26 at one end which is received in a suitable bearing in the arm 15 and the opposite end of the said cylinder is rovided with a hollow trunnion 27 which 1s received in a bushing 28 rojecting from the plate 25 into a suitable caring in the arm 18. The trunnion 23 on the cylinder 20 has a gear wheel 29 secured to its outer end and the trunnion 27 of the cylinder 21 has a gear wheel 30 secured to its outer end.

Because of the greater diameter of the cylinder 21, its longitudinal axis is located further from the central axis of the axle 1'2 in order to leave room between its surface and the sleeve 13 for the clamping rings 31 and 32 which hold the plate in position on the cylinder. On this account, the gear wheel 30 on the trunnion 27 of the larger cylinder is of greater diameter than the gear wheel 29 on the trunnion 23 of the smaller cylinder, the relation being such that when the cylinder 21 is swung on the axle 12 into operative position with respect to the cutter, the lowermost point on the wheel 30 will occupy the same position as that which the lowermost point on the wheel 29 occupied when the cylinder 20 was in operative position thereby making it feasible to utilize a single driving pinion 33 for rotating the cylinders of different diameters while in operative position under the cutter.

The driving pinion 33 is fixed on a short shaft 34 mounted in a bearing 35 formed in a cap plate 36 fixed on the outer end of the axle 12. The shaft 34 is provided with a hand wheel 37 for operating it. The plate 36 is centered and locked in position by means of a bolt 38 passing through it'and screwed into the end of the axle 12 and a dowel 39 set in the end of the axle 12 to one side of the center enters a socket in the plate 36 when the latter is in the proper relation to the axle and serves to prevent any rotary movement of the plate 36 with respect to the axle 12.

The plate 36 carries a spring actuated dog 40 which enters one or another of the sockets 41 in the end of the sleeve 13 to lock the latter in the proper rotary adjustment on the axle 12 to bring either the cylinder 20, the cylinder 21 or the table carried by the arm 16, into 0 erative osition below the cutter. -The p ate 36 a so has attached thereto arms 42 and 43 (see Fig. 2) on the ends of which are partial hoods 44 and 45, respectively, which hoods combine with caps 46 and 47 carried by the plate 25 to house the gear wheels 29 and 30, when the said wheels, together with their respective cylinders, are rocked out of operative position with respect to the cutter.

The outer surfaces of the cylinders 20 and 21 are screw threaded for receiving the plate holding rings, those hereinbefore referred to and denoted by 31 and 32, being made to register with the screw threaded surface of the cylinder 21, and those denoted by 48 and 49 being constructed to register with the screw threaded surface of the cylinder 20, a plate held by these rings being indicated by 50, Fig. 3.

The flat table held by the pair of bifurcated arms 16 is denoted by 51. It is secured at its opposite ends to the branches of the arms, as shown at one corner, Fig. 2, by the bolts 52, 53, which pass through a depending portion of the table into a branch of one of the arms 16 it being understood that a similar fastening is repeated at each of the four corners of the table. The table 51 is provided with suitable clamps 54 and 55 for ocking the plate to its face.

The clamp 54 is placed in the position desired and locked by means of the wheel 56 in a manner well known in the art while the clamp 55 is adjusted by engaging it with some one of the holes 57 in proximity to the edge of the late and is then forced into contact with t e plate by being slid along the surface of the table by means of the lever 58.

In rocking the table 51 into position beneath the cutter if its advance corner should be so high as to interfere with the cutter the entire cylinder and table supporting frame may be lowered by operating the screw 5 heretofore referred to and when the table is in register, it may be again bodily lifted to bring the plate into position to be operated upon by the cutter.

The structure hereinabove described admits of moving the cylinders of varying diameters into position by a simple swinging of their supporting frame and provides at the same time for operating upon flat plates thus making the machine quite universal in character and saving a great amount of time and labor which has heretofore been commonly expended in removing a cylinder and placing another in osition.

What I c aim is 1. The combination with a cutter, of a plurality of horizontally arranged cylinders of difierent sizes for supporting on their curved faces plates to be cut and means whereby one or another of the cylinders may be moved at pleasure into 0 erative relation to the cutter with its curve face opposed to the cutter.

2. The combination with a cutter, of a work supporting cylinder and a work supporting table, a frame common to the said work supports and means for moving the frame to bring the cylinder or table into operative relation to the cutter at pleasure.

3. The combination with a cutter, of a plurality of work supporting cylinders of different sizes, a moving support for bringing one or another of the cylinders into operative relation to the cutter and gear for rotating the cylinders when in such operative relation.

4. The combination with a cutter, of a plurality of work sup orting cylinders of different sizes provide with operating gears, a driving pinion for rotating the cylinders and means for moving the several cylinders 1 one at a time into operative position with their gears in engagement with the driving pinion.

5. The combination with a cutter, of a sleeve mounted in rotary adjustment on an axle, work supporting cylinders of different sizes carried by the sleeve, a cylinder driving pinion supported by the axle, gears carried by the cylinders in position to be engaged with the said pinion and means for locking the sleeve in different rotary adjustments.
